14 Claims. 1 This invention relates to automatic vending machines which the purchaser operates by inserting coins and depressing selector buttons corresponding to selection of articles dispensed by the machine. The improved apparatus is intended for general utility in vending packaged commodities which, because of bulkiness and diversity in shape and size, have heretofore been considered unsuitable for machine vending.

Selective vending machines are in extensive use in dispensing special products such as cigarettes and other small articles but these usually are special machines limited to one particular product. In other words, they have fixed magazines and associated delivery mechanisms and are used in vending widely used products of such nature that the volume of sales justifies the cost of the machines; however, it is not economically feasible to utilize special machines for general merchandising because of the great range of package sizes involved.

The present apparatus is intended to provide a flexible unit which is adaptable to various sizes and shapes of merchandise within its range of adjustment, whereby the machine may be installed in stores and other establishments to vend standard items which are purchased usually as a matter of routine. It is contemplated as one example, to install the machines in department stores to vend ready-to-wear articles such as socks shirts, underwear and many other items which do not require individual fitting or alternations. In a store of this character, the selection offered by one machine is insufiicient to meet the great number of items, grades and sizes necessarily carried in stock; consequently, it is preferable to group a series of machines in batteries to provide one or more self-service departments whereby the purchaser may make his selections in a rapid, convenient manner and thus conserve time and reduce merchandising costs.

The improved apparatus embodies a series of adjustable magazines to accommodate various packaged items, an individual mechanism associated with each magazine for dispensing the packages, and respective selector buttons for actuating the mechanism of a selected magazine upon insertion of coins and operation of a selector button. The magazines are located in a rearward section of the machine and the delivery mechanisms and associated selector buttons are locatedqin' the forward portion, the arrangement being such that the machines may be built into the'wallfof a self-service department with the front portions presented to the purchaser and .2 the magazines disposed in a service area onthe opposite side of the wall in position to be refilled continuously by the store clerks without interfering with the purchasers and without interrupting the operation of the machines. Although the machines are intended primarily for this type of operation, it is contemplated also to install the units individually at desirable locations in the store, in which case the machine is en-. closed in a suitable housing provided wth doors for periodic refilling of the magazines,

The primary objects of the invention have been to provide a simple and reliable dispensing mecha-v nism which is operable in conjunction with ad+ justable magazines to dispense relatively large packages of diverse sizes and shapes without requiring any adjustment in the dispensing mechanism; also, to provide an improved delivery apparatus which displays in full view of the pur..-: chaser the identical article which is delivered upon actuating a given selector button so as to simplify the operation of the machine. Because a great deal of purchasing is done by housewives who are inexperienced in dealing with machinery, and arrangement of this kind isof particular advantage in avoiding mistakes in selection since the packages are clearly marked and, in many instances, consist of well known products bearing distinctive trade marks well known to thepurchaser. The front portion of each machine is equipped with windows through which thepackages are displayed and the selector buttons are closely related to the respective windows. for positive identification and selection of the desired article.

Briefly, the mechanism for dispensing the packages consists of an ejector mechanism for each magazine cooperating with a delivery tray at the forward portion of the machine arranged.

to sustain a package beneath an observation window for inspection before purchasing, the ejector mechanism serving to advance the packages from the magazine to the tray and the tray being arranged to dump the package into a chute for delivery directly to the purchaser upon operation of the selector button for that particular tray. The cycle of operation is initiated when p the selector button is depressed, first to dump the package from the tray into the delivery chute, then to return the tray to a level position, after which the mechanism advances the next package from the magazine to the delivery tray where it remains until the next purchaser depresses the button to repeat the cycle of operation.

Further objects of the invention have beento simplify the ejectors by which the packages are advanced from their magazines by utilizing a single power unit and coupling the ejectors electrically by operation of the selector buttons so that upon each cycle of operation, the selected ejector only is activated; also to provide delivery trays in conjunction with the ejectors which are tilted by the related ejectors to deliver the displayed package as soon :as a selector. button. for that tray is depressed. The apparatus is arranged to return the tray to its display position before the next package is advanced from the magazine; otherwise expressed, :the iefiectorsand trays operate in timed relationship to deliver the package which was advanced to the tray at the end of a previous cycle and then to reset the tray and place the next package uponit before stopping. Thus, even if the magazine is empty, the last package is in position for delivery and after that package is delivered, the tray of course remains empty. The purchaseris guided in his selection by the packages displayed, and consequently: will not :select an empty :delivery tray.

zAnadditional objectha's been to prevent the traytf'rom beingftilted'eve'n.ifiorce is applied and thus to prevent theft of the package displayed upon it. For this purpose, the tray is tilted by artoggle link-age system which sustains the tray in .its display position with the linkage straightene'd in atlocking position. The joint of the linkage is coupledtothe related ejector-and tilts the tray by impartin'g a scissorsmotion to the toggle 'imks-td'uring'the retracting movement of the ejector anda'rrange'd-to lock the links in straight position at "the end of the package advancing movement of the ejector.

iGenerally described, the apparatus consists of a series of magazines which are spaced apart sufii'ciently 'to enable the magazines to be adjusted to accommodate various package sizes, each magazine being associated with a delivery trayarranged :toreceive :the articles as they are pus'hed'irom ithe :lOWBl" end :of the .magazine and to :support the article beneath the observation "windowiorinspection by the purchaser. Each magazineiis provided with an ejector arm which swings in an are carrying at its upper end an ejector finger which engages the lowermost article contained in the magazine and pushes the earticleiorwardly to itsreceiving tray.

lThepowerssystem which is common to all the ejectors, provides a. controlled cycle of operation by means of an electrical control system which, .lnturn, .is energized when the proper number of coins are inserted in the coin mechanism and a selector button depressed. The respective ejector arms normally remain inactive during the *cycle of operation except the-arm for a particular magazine which is coupled electrically to the driving system in response to operation of the .se'iector button for that magazine. As above noted, the ejector arm :is coupled directly to its associated :delivery tray in such manner that the tray is tripped to discharge its article-during the rearward stroke of the ejector arm and is returned to its supporting position during the forward or package advancing stroke-of the arm, but before the package is advanced to the tray. When the machine completes its cycle, the next article-to be delivered thus is in display position upon the tray "ready fordelivery during the first :stage of the next cycle.

,EIhe connection between the ejector arm and its delivery tray consists of a pair-of toggle levers which are pivotally connected together at their intermediate ends with their outer ends pivctally connected to the tray and to a fixed pivot point. A link is connected to the intermediate joint of the levers and its opposite end is connected to the ejector arm to operate the toggle levers in scissors fashion. The toggle levers include stops which lock them in a substantially straight position slightly beyond dead center with the tray in its display position and .a spring is applied to the leverstourge them normally in this direction. As the ejector arm Swings rearwardly during the first stage of its cycle, the toggle arms are drawn rearwardlyaga-ins-t the spring pressure, causing the tray to tilt and discharge its contents upon a chute which communicates with a delivery opening at the front of the machine. As the ejector moves .forwardly, the spring urges the toggle levers in tray closing direction so that the tray may be closed to receive the next package before the ejector arm advances it.

Various other features and advantages of the invention will-be clearly apparentfrom the specification with reference tothe drawings disclosing a preferred embodiment vof theinvention so that those skilled in the art will comprehend readily the various modifications to which the invention is susceptible.

Figure 16 is a sectional view taken on line |6l6, Figure 1, detailing the structure and arrangement of one of the magazines.

Figure 17 is a diagram illustrating generally the electrical circuit which controls the operation of the machine.

Described in general with reference to Figure 1, the various parts of the machine are mounted upon an angle iron frame indicated generally at 1, having a sheet metal housing 2 which encloses the mechanism either in its entirety or partially, depending upon the type of installation; Machines which are to be utilized individually are completely enclosed by housings which have door openings for refilling the magazines; those intended for built-in use are enclosed at the forward portion only. In either case, the forward portion of the housing is provided with a delivery opening, as hereinafter disclosed. The rearward portion of the machine,

indicated generally at 3, contains the merchandise magazines 4 in its upper portion and corre-- sponding ejector mechanism 5 arranged to feed the packages 6 from the magazines to the delivery trays l which extend forwardly from the lower ends of the magazines. The delivery trays are mounted within the forward portion 8 in cooperating relationship with respective delivery chutes!) so that the packages are advanced sequentially from the magazine to the delivery tray and from the tray to the delivery chute.

The delivery chutes are sharply inclined downwardly and terminate at the delivery openings [0 (Figure 4) formed in the casing at the front portion of the machine. The end of the chute is provided with an end flange H to retain the package in a position to be picked up conveniently by the purchaser.

The operating characteristics of the machine are disclosed most clearly in Figures 1 and 3, the ejector being shown in Figure l in its stationary position with a package resting upon the delivery tray ready for discharge; and in Figure 3 the ejector mechanism is in the retracting stage of its cycle with the tray tilted to dump the package. In other words, at the end of each cycle, a package 6 is placed upon the tray so that during the first stage of the next cycle the package so positioned is discharged concurrently with retracting movement of the ejector apparatus. During the second stage, the next package is advanced from the magazine toward the tray, but before it reaches the tray, the tray is. returned to its level position to receive the package. This arrangement permits the pur- "chaser, to observe the identical package which Will be delivered when he operates the machine, the forward portion of the casing for this purpose being provided with windows l2 directly above the trays and associated delivery'chutes (Figures 1 and 4) The control system includes a coin mechanism (not shown) which consists of a commercial structure in electrical connection with the power @unit. indicated generally at l3, Figure 2. The

power unit includes a cycle control switch arrangement which deenergizes the unit after one complete cycle of operation. The cycle of operation is initiated by inserting the proper coins into the coin mechanism, depressing one of the selector buttons l4 (Figure 3) corresponding to the desired package, whereupon the power unit is energized to execute one cycle of operation.

As above noted, each machine is provided with a series of magazines and cooperating ejector systems which are actuated selectively by the power unit I 3. Each machine constitutes a complete unit in and of itself and may be installed individually in stores and other business establishments for merchandising packaged articles or, on the other hand, a series of machines may be placed side by side in a special department devoted to vending machine merchandising. If the machines are installed in batteries, it is preferable to place them in a wall opening and present only the forward or delivery portion ill to the purchaser, with the rearward magazine section 3 at the opposite side of the wall so that the magazines may be replenished directly from a supply room remote from the purchaser's room without interfering with the operation of the machines. The specification is directed to a single dispensing machine since the machines of the group are identical and operate as independent units.

Magazines As illustrated in Figures 1 and 16, the packages are maintained in vertical stacks in the magazines indicated generally at 4, there being provided in each machine a plurality of magazines and a corresponding ejector apparatus and delivery tray for each magazine. The articles to be dispensed are packaged preferably in boxes or cartons of a given size for each article to adapt the articles to the magazines. The magazines each consist of vertical angle irons indicated at l5 and I6, arranged to embrace loosely the four corners of the packages which are stacked within them, with the lowermost package of the stack resting upon a horizontal support rail I! which is traversed by an ejector finger 18, as hereinafter disclosed in detail. In order to adapt th magazine to receive various sizes and shapes of packages, the angle irons are adjustable with respect to one another, as detailed in Figure 16. As shown, the forward angle irons I5 are adjustably secured to a horizontal rail l9 which, in turn, is secured to the forward angle irons of the frame I. The adjustable attaching means for the magazine angle irons is illustrated at the lower end only but it will be apparent that the same construction may be utilized at the upper end to maintain the angle irons securely in their parallel relationship.

As shown, the forward angle irons l5 are secured to the support rail i9 by'means of wing nuts 20 which are screw-threaded through U- shaped brackets 2i, welded or otherwise secured to the angle irons l5. Upon loosening the wing nuts, the angle irons may be shifted laterally with respect to each other to accommodate'the lateral dimension of the package to be con tained therein. It will be observed in Figure 2, that space is provided between adjacent magazines so that they may be expanded laterally to accommodate packages larger than those disclosed. It is to be observed also that the several magazines of a given machine may be adjusted for various sizes. of packages within the prescribed limits; also, ma the machine can be convertedito the desired size without any change other than. the actual change in magazine size, since the ejector finger I8. is arranged to operate over a fixed path which is slightly longer than the maximummagazine size.

The rearward angle irons l6 of the magazine are supported by horizontal rails 22 having their ends "welded or otherwise secured to the forward angle irons as at 23. The rearward angle irons are secured to the bars 22 by'wing nuts 20 passing through brackets 21 and engaging the bar 22 in the same manner as the forward angle irons. .It will be apparent therefore that the magazine size can be changed widthwise and lengthwise. The width .is adjusted by loosening th'ejfront wing nuts and shifting the angle :iron and rails 22 laterally relative to the-support rail 11.; and the length is adjusted by loosening the 'wingnuts and shifting therearward angle irons I5 with respect to the forward ones. In adjusting the width dimension of the magazine, it is preferable to maintain the magazine assembly in centered relationship with respect to its ejector finger.

As shown in Figure 6, the ejector finger IB is arranged to be tripped by the package to an inoperative position during its retracting movement and to swing by gravity to a vertical position after passing the rearward edge of the package to advance the package, as shown in Figure '7. The rearward angle irons iii of the magazine extend downwardly toward the guide rail H to engage the rearward end of the lowermost package to prevent the package from "being pushed rearwardly during the rearward travel of the ejector finger, and the forward angle irons l5 terminate above the lower package, as at 24 (Figure 1'), to permit the package to be pushed forwardly during the delivery stroke of the ejectorfinger.

Ejector apparatus Each magazine is equipped with an individual ejector mechanism 5, which may be selectively actuated to feed the packages from the magazine to a related delivery tray, and each tray is connected to the ejector mechanism for operation in conjunction with that particular unit. Thus, the ejector and delivery mechanism for each magazine operate in unison independently of the other magazines to deliver the selected package and advance a succeeding package from the magazine to the tray upon each cycle of operation. As previously described, the ejectors which .serve the several magazines are powered from a single power :unit and are individually connected to thexpower unit upon depressing in related selector-button.

Described in detail with reference to Figures 1 and 5, each ejector consists of a swinging arm assembly 29 having its lower end pivotally mounted upon arock shaft 3b journalled in bearings 31 which are secured to the base of the machine frame. As shown in Figure .3, .rock shaft 38 extends crosswise of the machine and provides a common pivotal support for all of the ejector arms of the machine, a bearing being provided betweenfthe respective arms to stabilize the rock shaft. The bearings are of the split type, each consisting :of a bottom section 32 secured .to the base and a cap section 33 secured by screws to the bottom section. The arm assemblies naturally swing in an arc and :order to move the ejectorxfinger l8. a horizontal path with respectto the magazines, each arm assembly 29 is of sectional construction consisting of a lower arm 34 which is loosely pivoted upon the rock shaft and an extensible upper section 35 which carries the ejector finger 18. The lower arm is slotted as at 36-36 and the upper section is slidably joined to the lower by means of headed rivets or shoulder screws 3131 fixed in the upper section and slidably engaged in the slots.

As detailed in Figure 5, the upper :end of the extensible section 35 is confined for horizontal movement by channels 3838 which are welded or otherwise secured to the rail I1 immediately beneath themagazine. The ejector finger i8 is pivotally mounted upon the upper end of the extensible section 35 by a pivot pin 40 which passes through the arm 35 and ejector finger. The pin extends beyond the opposite sides of the ejector finger and carries rollers 4l4l which are confined in the channels 38; thus, pin 40 pivotally mounts the ejector finger and also supports the extensible arm section. As the lower arm swings through its arc of movement, the extensible section slides longitudinally with respect to the lower section 34 to compensate for the arc of swing. As shown in Figures 2 and 5, the rail I! is provided with longitudinal flanges 42-42 upon which the channels 38 are welded or otherwise secured, and the ejector finger I8 and arm section 35 are guided accurately with respect to the rail ll with the upper end 43 of the ejector finger extending above the plane of the rail I! in position to engage the package resting upon the rail. In order to reduce friction, the rail H is provided with a pair of longitudinal beads 44-44 arranged to support the package (Figure 2).

The ejector finger I8 is formed preferably of sheet metal and is generally U-shaped in cross section to provide a pair of side flanges 4545 for mounting purposes. A pair of angle brackets 4646 are secured upon the inner surface of the finger to provide spaced flanges 41-41 which embrace the opposite sides of arm section 35 to stabilize the finger angularly with respect to the arm section. The lower portion 48 of the ejector finger depends downwardly a sufiicient distance below the pivot pin to to cause the finger to hang by gravity in a vertical position with respect to the arm. During the retracting motion of the ejector finger (Figure 6), its upper end 43 contacts the underside of the package and is tripped te the position shown: after passing the rearward end of the package, the finger drops to the vertical position shown in Figure 7. Upon engaging the package, the finger is locked in its engaging position by engagement of its lower portion 48 against the section 3.5 to slide the package from the magazine and advance it to the delivery tray.

Selective driving mechanism Each arm assembly 29 is loosely pivoted upon the shaft 30 and is swung through its operating cycle by means of a respective driving lever 50 which is non-rotatably secured to the rock shaft 3! As shown in Figure 2, the driving lever is provided with a hub 5| secured by a'pin 52 to shaft 30 and the lower arm .34 of the ejector assembly is maintained in position alongside the driving lever by a collar 53 which is secured to shaft .30 by .a pin .or screw 54. During the cycle of operation, all of thexdriving levers swing in unison through :a cycle of oscillation but the ejector arms 'remaimstationary unless they are 9 coupled to the driving levers. The ejector arm for a selected magazine is coupled to its driving lever by depressing a selector button I4 which energizes a solenoid operated latch, generally indicated at55, there being provided an individual solenoid latch unit for each lever.

The electrical system for energizing the solen'oids is described in detail in connection with the electrical circuit illustrated in Figure 17 and the levers 50 are driven by a power unit interconnected in the circuit. For present purposes, it is sufiicient to note that when the coins are inserted in the coin mechanism and a selector button depressed, all of the driving levers are oscillated by .rock shaft 30 and the selected ejector arm is coupled by a solenoid latch 55 to its driving lever to operate through its cycle. The power unit includes a cycle control apparatus arranged to cause the mechanism to operate through one complete cycle and thento deenergize automatically at the end of the cycle. The construction and operation of the power unit and cycle control apparatus is later disclosed in conjunction with theelectrical circuit.

" The general arrangement of the solenoid operated latches 55 is illustrated in Figure 2 and oneof the latches is detailed in Figures 13 and 15. As shown, the latch units are mounted upon the outer or swinging ends of the driving levers, each solenoid; having its coil enclosed by a housing 56 which is secured preferably by screws to its lever 50. The lever 50 is formed of angle irons to provide the necessary stiffness and the housing 56 is nested within the angle section, as shown in Figures '13 and 15. The solenoid armature is provided with a plunger 51 extending through the housing 56 and adapted to actuate a coupling latch 58 which is pivotally mounted as at 60 upon the driving lever in position to engage the ejector arm assembly when the solenoid is energized, as shown in broken lines in Figure 15. The coupling latch is shaped like a bellcrank, having one limb 6i arranged to engage, the ejector arm assembly and an arm 62 arranged to' engage an inclined release bar 63 which swings the lever 58 to its inoperative position at the retracting stroke limit of, the driving lever in the manner shown in Figpres 14 and, 15.

1,. The solenoid is'a conventional structure and its armature is spring loaded to urgethe plunger normally inthe outward position, .as shown in Figures. 13'and'14. A'driving connection is established between the solenoid plunger and coupling latch by means of a lug 64 welded or otherwise secured upon the end of the plunger 51 and passing at right angles'through a slot 65 formed in the driving'lever 50. The extended end of lug .6] engages thelimb 62 of the coupling latch and, upon being energized, the solenoid plunger re tracts and pulls the coupling lever from its inoperative position shown in full lines in Figure toits coupling position, as shown in broken lines. The two latch positions are shown also in Figure 2, the latch for the left hand ejector arm being shown inits coupling position, while ,the right handclatch is shown in its uncoupled position, 1

The solenoid latch operates only to retract a selected ejector arm to a position behind the magazine and is released when the armis retracted; in .other words, the latch is activeconly l0 bly and occupies a position angularly advanced with respect to the ejector assembly; therefore, upon energizing the selector solenoid, the solenoid latch will swing to its coupling position prior to actual engagement of the latch with the ejector arm assembly. This arrangement prevents binding of the latch against the ejector which would interfere with proper operation; When the solenoid is energized, the power unit begins its operating cycle, causing the driving lever to swing rearwardly until its coupling lever contacts the ejector arm to drive'it rearwardly, as shown in Figure 6, continuing in this directi n until it reaches the fully retracted position shown in broken lines in Figure 7. During the latter portion of the rearward swing of the driving lever and ejector arm, the coupling limb 62" contacts the underside of the stationary release bar 63 and begins to swing the latch toward uncoupling position. Upon reaching its rearward position, the latch is completely uncoupled from the ejector arm and occupies the position shown in Figures 14 and 15.

The driving lever now begins to swing forwardly until it contacts the abutment arm 66' which is fixed upon the ejector arm,the end of arm 66 being bent angularly as at 61 to provide an abutment which is engaged by the driving lever. It will be observed that the abutment 61 is spaced sufiiciently from the ejector arm to provide an overtravel as the driving lever moves in the ejecting direction. The driving levers are powered by a driving disk 68 connected 'bya pitman 69 to one of the levers. The disk forms a part of the power unit and produces a crank motion through one cycle of rotation each time the power unit is energized, as hereinafter described. The arrangement is such that the actual travel of the ejector does not depend upon precise stopping of'the disk at the end of its cycle, instead the ejector arm stops when the disk completes its cycle eventhough the driving lever may reverse its direction before stopping.

. As the ejector arm moves forwardly, it contacts the rear edge of the lowermost package, as shown in Figure '7, and thrusts the package forwardly until it is advanced to the delivery tray, as shown in Figure 1. It will be observed at this point that the travel of the ejector arm is considerably greater than is necessary to eject the package size illustrated. This permits the magazines to be be adjusted for various sizes of packages without changing the stroke of the ejector mechanisrn. Otherwise expressed, the forward edge'of the package is located at a fixed position and the rearward edge varies in accordance with the package length; therefore, the maximum length is limited only by the rearward stroke limit of the ejector. The width of the packages is, of course, limited by the lateral spacing between the mag{- azines.

Delivery mechanism As above noted, the ejector finishes its cycle of operation with a package ejected from the magazine and resting upon delivery tray 1 in a position to be viewed by the purchaser; When the selector button for that particular package is depressed, the tray is tilted from the position shown in Figure 1 to that shown in'Figure 3 causing the package to slide down' the tray to the delivery chute 9 to bezpickedup by the pur- This occurs before the next package tilted as the ejector arm. retracts and being levelled before the next package is advanced by theejector from the magazine. For this purpose, the tray is connected to the ejector arm for direct actuation in time with ejector movements as hereinafter described.

- Described in detail, the tray is supported and actuated by a toggle joint indicated generally at 1-0 consisting of a pair of limbs 11 and E2 pivotallyconnected. together as at 73 to provide a knee joint and having their respective opposite ends pivotally connected to the base or the ma chine as at 74 and to the tray as at 15. These connections are made by means of angle brackets 16 which are spaced to receive the limbs II and '12 with pivot pins 14 and 15 joining the limbs to the brackets {Figures 3 and 4). A scissors motion is imparted to the limbs by a link 71 con-- nected to the limbs at the intermediate pivot point; .13 having its opposite end pivotally connected as at 18 to the ejector arm 29. Asthe ejector arm retracts,the limbs swing to the position shown in. Figure 3 causing the tray to tilt to an inclined position in alignment with the discharge chuteand to return to level position before the ejector arm advances the next package from the magazine to the tray.

In order to lock the tray in level position, there isprovided at the knee joint a stop plate 86 which is welded as at 8! to thelower limb I2. This plate engages the upper limb and locks the limbs with respect to one another in their straightened position with the pivot point 13 slightly beyondthecenters of the'upper and lower-points 14-and'15; Downwardthrust upon thetray thus is resisted by the stop plate 8i! since the relationship of the pivot points causes the limbs to swing in that direction.

As detailed'in Figures 8 and 9, a spring 82 is applied to the knee joint to urge the limbs normally totheir straight position. Thus, it is impossible totilt the tray except by angulating the limbs. Spring .82 consists of a coil 83 engaged upon a stud 84 forming a part of the pivot pin 13* and the coilis provided with arms 85-85 having their ends bent to form hooks 8686 for engagement with the edges of the respective limbs. Thespring arms 85 arearranged to bias the toggle limbs against the-stop plate Bil-such that the spring resists the tray tilting motion imparted by the link 11 during the retracting movement of the ejector arm. The spring exerts sufficient force to return the toggle limbs from their angular relationship shown in Figure 3 so as to level the traybefore the ejector arm advances the next package to the tray.

The rearward end of link 1T includes a slot 88 engaged by the pin 18 of the ejector arm whereby the tray is tilted by positive engagement of the pin against the end of the slot during retracting of the ejector arm and is returned by spring 82 and controlled by the pin during the package advancing movement of the ejector; In other words, the spring exerts the actual force for returning the tray to its level position with the pin engaged against the end of the slot until the tray islevelled. During the final advancing motion of theejector arm after the tray is levelled, the pin 18 traverses the slot until it resides against the right. hand end. of slot 88, as shown in. Figure l. The toggle limbs thus are locked positively by the link. 1.! and ejector arm assembly so that it is impossible to force the limbs rearwardly; consequently, the tray cannot be tilted by means other than the normal operation of themachina Power unit As above noted, the several ejector and delivery assemblies for the magazines are driven from a common source of power and the, selected mechanism is coupled to the driving levers. 50 by the. solenoid operated coupling latches 58. The power unit is best. illustrated in Figures 11 to 15 inclusive and consists of an electric. motor 89. cou-- pled to the driving disk 68. through reduction gearing, the disk being connected to onev oflthe driving levers 50 by the pitman.69, asabovenoted, to actuate the several driving levers in unison. A cycle control. apparatus. is. associated with they power unit toprovide one-revolution, corresponding toone cycle of operation, each time the unit. is energized.

Described with reference. to Figures 1 and 11. the shaft. of motor 89 is provided. with aworm 9J1 meshing with a worm wheel 92 fixedv to a vertical shaft 93 which is journalled inagbracket 94. secured to the motor. The lower end of shaft 93 includes awormflfi (Figure l.) meshing with a second Worm wheel 96 carried by a horizontal shaft 9] also journalled in bracket 94'. Thedriving disk 68; is non-rotatably secured upon the extended end of the shaftS'l and isir otated at. a relatively low speed by reason of the reduction gearing. One end of. pitman. 69. is, connected to the disk by the pivot pin 98.and the opposite. end is connected to one of the driving arms 50. by means of a second pivot pin 1.00. (Figures. 13. and 14) Since the severaldriving levers-50 arenonrotatably fixed to the rock shaft. 3.0,. they; swing in unison through aforward and returnstroke during one revolution of disk 68.. and the selected ejector arm 29 is drivenby thearm to-which it. is coupled.

As illustrated, the cycleis controlledbyan automatically operated switch assembly till which is interconnectedelectrically in the control system and which is actuated. mechanically by-the driving disk to deenergize the motor. and apply a brake at completion ofone, revolution of the. disk. Alternatively, it is contemplated to utilize a relay connected mechanically to the disk and having a. series of contacts to control the cycle. In the present form, mercury switches are utilized. Of these, switches [02. and I03 are normally open and, switch Hi4 is normally closed. the purpose of this arrangement being more clearly explained in conjunction with the control circuit. The arrangement is such that. themercury switches are maintained normally in level position, as shown in Figure 12', with switches Hi2 and I O-3'open' and switch 164 closed. They are tilted tothe position. shown in broken lines to close switches I02 and I03 and open switch I04 when one of the selector buttons is depressed to initiate a cycle of operation.

For this purpose; the switches are mounted upon a tilt platform Hi5 which is connected mechanically to a solenoid -l 06' (Figure ll and" arranged to tilt the platform when thesolenoid is energized by depressing one of the selector buttons. The mercury switches are adapted to establish a holding circuit for continued operation of the motor for one cycle of rotation; At the end of the cycle, the platform is returned to level position by the driving. disk 68. For this purpose, the disk 68 includes a skid or cam m (Figure 13) adapted to engage a pin I08 which isconnected to the tilt .platformto return the tilt bracket to its level position. As. shown in. Figures 11 and 12. the solenoid I96 is. energized to tilt the switch platform 1.05, moving the. pin 10.8. tQ-theshown,

position and causing the motor to rotate the disk in the direction indicated by the arrow. Upon completion of the cycle, the cam I01 engages the pin I08 and returns the platform to its original position, thereby automatically deenergizing the motor circuit and applying an electric brake III] (Figure to stop the motor.

Described in detail, the tilt platform I05 is pivotally mounted upon a bracket I I2 by a pivot pin H3 passing through the bracket and the limbs I I4I I4 forming a part of the tilt platform. The upper portion of the tilt platform includes a laterally extended arm II5, pivotally connected by pin I I 6 to the outer end of the solenoid plunger III. The connection is made by the upwardly bent arm portion IIS passing .through a slot formed in the end of a plunger I II, the angular extension I I8 preferably being slotted as at III! to accommodate the swinging motion of the tilt table (Figure 11). The pin I58 which is engaged by the cam ID'I is secured directly to the end of the solenoid plunger I I1 and extends across the circumference of the disk with its outer end slidably supported upon an angle bracket I25 forming a part of the base I2I which supports the solenoid. When cam I51 engages pin I58 and returns the tilt platform back to its level position, the motor is deenergized and the driving disk overruns slightly by inertia to carry the cam IIII to the position shown in Figure 13. When pin IIIB is reset, the solenoid. plunger is pulled to its extended position ready to initiate the next cycle of operation upon being energized.

Electrical control system The coin mechanism, cycle control apparatus and selector buttons are interconnected electrically, whereby upon insertion of the correct amount of change into the coin mechanism, the circuit is conditioned for operation; however, actual operation'is deferred until one of the selector buttons is depressed to trip the cycle control apparatus and to couple the selected ejector arm to its driving lever. The circuit illustrated in Figure 117 is adapted to one type of coin mechanism and it will be apparent that other coin devices may be utilized, in which case, the circuit will be altered as required. The coin mechanism is a commercial product and a detailed description of its component parts is omitted since such apparatus is well known in the art.

The mechanism disclosed in the diagram consists of a totalizer, a reset device and a coin dump, such parts being suitably arranged as a unit which is installed at one side of the machine. The parts are indicated in the diagram by the labeled rectangles, each part being suitably interconnected in the circuit as shown. Thus, the totalizer unit closes the circuit for operation when the correct number of coins have been insorted and a selector button depressed, the reset device resets the totalizer for the next operation after the cycle is initiated, and the coin dump discharges the coins into a receiver after the cycle is initiated. In the diagram, the cycle control switch is illustrated as a relay having two normally open contacts which correspond to the mercury switches I02 and I03 and a normally closed contact corresponding to the normally closed mercury switch I04. Also, the mechanical connection between the motor 89 and driving disk 68 is illustrated diagrammatically as a direct connection instead of the gear reduction system :actually employed. The control system is best understood by analyzing its operation when a cycle of operation is initiated.

As shown, the circuit is powered by the lines LI and L2 and is illustrated with three selector buttons I4 and associated coupling solenoids 55 although the operation is the same regardless of the number of ejectors and corresponding solenoids. The totalizer is arranged to energize line I23 from line LI when the coins have been inserted so that a circuit is established through line I23 to the contacts of a selected button I 4 to energize the winding 55 of the related coupling solenoid. The circuit is completed by way of line I24 which is common to the terminals of the coupling solenoids 55, through line I25, to winding I55 of the cycle control solenoid, to line I26 and through the normally closed contact I04 to complete the circuit by way of line I2'I to L2. Thus, when a selector button I4 is depressed, a corresponding coupling solenoid is energized, the cycle control solenoid is energized to close the normally open contacts I52 and I53 and to open the normally closed contact NM. The normally closed contact I54 causes the windings '55 and I06 to be energized momentarily when the selector button It is depressed but prevents the mechanism from operating for more than one cycle. When the normally closed contact I is opened, the latch solenoid winding 55 and cycle control winding I 58 are deenergized; however, their respective plungers remain in retracted position until they are extended mechanically by operation of the machine.

As soon as winding I06 is energized, a circuit through the motor is established by way of line LI, branch line I28, through the closed contact I52 to lines I29 and I30, through closed contact I53 to line I3I. From line I3I the circuit branches to line I32, through the motor to line I21, thus completing the circuit from LI through the motor to L2 to start a cycle of operation.

Briefly, therefore, when the selector button is depressed, a circuit is established through the totalizer to energize the selected solenoid 55 and to energize the cycle control solenoid I06 through normally closed switch I54 to line L2. When cycle control solenoid I d6 is energized, it opens normally closed contact IM to deenergize the solenoids 55 and I56; however, the coupling latch 53 which is actuated by the winding 55 remains in coupling position until the latch is retracted mechanically by the release bar 63. Also, the cycle control apparatus IIlI remains inenergi'z ing position until it is returned to deenergizing position by engagement of cam III'I withpin I08 at the end of the cycle. The motor will thus continue to run after the button I 4 is momentarily depressed by reason of the holding circuit established through the cycle control apparatus.

The closing of contact I02 completes a circuit from line LI through contact I52 to line I29 and through the reset device to line L2. When contact I53 closes to energize the motor, the coin dump is energized from the motor line I 3| branch line I33, through the coin dump and through line I34 and I2! to L2. When the reset is energized, the totalizer is released from the position it assumed upon the insertion of the coins and is conditioned for the next cycle and when the coin dump is energized, it discharges the coins from the totalizer to a coin receiving section.

When the cam I07 contacts the pin I58 at the end of the cycle, the contacts I02 and I03will be opened to deenergize the motor and apply the accuse motor brake and the contact 104 "will :be closed so that the circuit for thessolenoid windings '55 and i365 again will ,be completed through the totalizer, rand selector buttonat the next cycle of operation.
